Mount Auburn, IL population, income and ZIP codes

Mount Auburn village is a very small community in Illinois, with 473 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #959 of 1,462 ranked by population — larger than 34% of them. The median age here is 40.6 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Mount Auburn village earn a median of $55,714 a year, 29.1% below the national figure of $78,538 and 25% below the $74,244 median for the 698 Illinois cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 12.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mount Auburn village is valued at $85,000, 72% below the national figure and 53% below the $179,100 peer median, while median gross rent runs $1,138 a month, 19.1% below the national figure, or roughly $13,656 across a full year. A household on the local median income would put about 24.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 1.5×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 94.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 473 residents, a handful of survey responses moves every median on this page. Compare Mount Auburn village against its county rather than against national figures.
